They are rarely encountered in otolaryngologic clinical practice, as they are usually located in the interscapular area, axilla, thigh, mediastinum, and retroperitoneum. We report an extremely rare case of a very large hibernoma in a 45-year-old man who presented with a 4-year history of neck swelling. Radioimaging was suggestive of a mass in both parapharyngeal spaces; the lesion was more prominent on the left side. The mass extended from C2 into the retropharyngeal space and superior mediastinum. Fine-needle aspiration cytology failed to yield a diagnosis. On surgical exploration, a tumor measuring 17 x 16 x 5 cm was removed and sent for histopathologic examination. Light microscopy was suggestive of a hibernoma. Staining with oil red O confirmed the diagnosis. To the best of our knowledge, a large hibernoma with such massive extension has not been previously reported in the literature.<\/jats:p>","DOI":"10.1177\/014556131309200424","type":"journal-article","created":{"date-parts":[[2019,1,9]],"date-time":"2019-01-09T15:12:22Z","timestamp":1547046742000},"page":"E18-E21","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Huge Hibernoma of the Neck with Extension into the Mediastinum"],"prefix":"10.1177","volume":"92","author":[{"given":"Ramanuj","family":"Sinha","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery (DOHNS), R.G.
